Relationship between circle are and radius squa0red is

A(Area) = pi r^2(radius squared).

pi is the constant of proportionality for ALL circles . It has a value of 3.141592.....

However for elementary school work , pi = 3.14

NB Remember to other relationship with circles for circumference.

C = 2 pi r = pi d

Learn and commit to memory ;-

A = pi r^2 & C = 2 pi r

The radius is half the diameter of a circle.

The diameter of any circle is twice its radius

The radius is half the diameter.

Area of a circle = pi*radius squared

As a cone will always have a base which is a circle, the relationship between the diameter and radius remains constant with that of a circle at any point of the shape. The radius is always 1/2 of the diameter. To figure out the volume of a cone you must first work out the radius, for the formula is: (1/3) x Pi x R^2 x h ^2 = Squared

'pi' is the constant of proportionality for ALL circles of whatever size. 'pi' has the values of 3.141592.... (to infinity). For school work pi = 3.14 For circle area A = pi r^2 circle circumference C = 2pi r = pi d Volume of a sphere V = (4/3) pi r^3 Surface Area of a sphere SA = 4 pi r^2 The ancients before Classical Greece noticed that when an mule/donkey was tied to a centre pole (the radius) and was driven around the pole in a circle to drive up water (circumference) there was a constant ; pi = 3.14.... e.g. diameter 'd' = 2r = 10 and circumference = 31.4 Then C constant of proportionality d Inserting the numbers 31.4 = constant X 10 constant = 31.4 / 10 = 3.14 This constant was named 'pi' ; the Classical Greek small case letter 'p', for proportionality. This constant held good for any circle of any size. Hence we have C = pi d => C = 3.14 d further calculations gave us the Area as A = pi r^2 => A = 3.14 r^2 'pi' is an Irrational number. Casually this means the decimals go to infinity and there is no regular order in the digits. Your calculator may show pi = 3.141592654, but this is only an approximation. # pi = 3.141592654...
